Julie Kavner Biography (Wikipedia)
Julie Deborah Kavner (born September 7, 1950) is an American actress. She first attracted notice for her role as Brenda Morgenstern, the younger sister of Valerie Harper's title character in the sitcom Rhoda, for which she won a Primetime Emmy Award for Outstanding Supporting Actress in a Comedy Series. She is best known for her voice role as Marge Simpson on the animated television series The Simpsons. She also voices other characters for the show, including Marge’s mother, Jacqueline Bouvier, and sisters Patty and Selma Bouvier.
Known for her improvisation and distinctive "honeyed gravel voice", Kavner was cast in her first professional acting role as Brenda Morgenstern in Rhoda in 1974. She received four Primetime Emmy Award nominations for playing the character, winning the award in 1978, the year that the series ended. Starting in 1987, Kavner started appearing on The Tracey Ullman Show. The Tracey Ullman Show included a series of animated shorts about a dysfunctional family. Voices were needed for the shorts, and the producers asked Kavner to voice Marge. The shorts were spun off into The Simpsons.
